The 6105CF is the only Bel Air variant built on a marbled carbon fiber handle — every other model in the 6105 series uses 6061-T6 aluminum. That single material difference changes the carry experience substantially: carbon fiber is lighter than aluminum, stronger per unit weight, and gives each knife a unique visual pattern in the marbled layup that no two pieces exactly share. The blade steel (CPM MagnaCut), geometry (reverse tanto), grind (flat), and opening system (SpeedSafe, Liner Lock) are identical across the Bel Air series. The 6105CF is the material-distinct piece in the lineup and the closest the platform gets to a custom knife specification.

CPM MagnaCut was designed from the ground up by metallurgist Larrin Thomas and produced by Crucible Industries to outperform the previous generation of powder-metallurgy steels across all three primary categories simultaneously. Compared to CPM-S35VN, CPM MagnaCut delivers significantly better edge retention, equal or better toughness, and vastly superior corrosion resistance — it approaches the rust resistance of H1 steel while maintaining the hardness and easy sharpenability you'd expect from a premium stainless alloy. For daily pocket carry, that means a blade that holds its edge longer between sharpenings, resists moisture better, and still resharpens on a standard bench stone without fighting you.

Carbon fiber is stronger than both aluminum and G10 at equivalent thickness while weighing significantly less — it has one of the highest strength-to-weight ratios of any handle material used in production knives. In practice, a carbon fiber Bel Air will feel noticeably lighter in the pocket than the aluminum variants, and the handle will not flex, warp, or absorb moisture the way some composites can. The surface of marbled carbon fiber is smooth rather than textured, so grip relies on handle contouring and palm swell rather than aggressive texture — it's a secure carry material for most EDC tasks, though buyers who need maximum grip in wet conditions sometimes prefer G10 or Micarta for hard-use roles.

A reverse tanto features a spine that curves downward to meet the edge rather than the angular clip of a traditional tanto. The result is a reinforced, mass-forward tip that concentrates cutting force on a small contact area — ideal for controlled puncture, box work, strapping, and any task where tip precision and strength matter. The flat grind on the Bel Air keeps the edge versatile for slicing and general EDC tasks as well, so the reverse tanto geometry does not sacrifice utility in exchange for tip performance.

The Bel Air 6105CF is a SpeedSafe assisted-opening folding knife — not an automatic or OTF. It requires manual thumb stud pressure to initiate opening, which places it outside the federal definition of a switchblade. That said, assisted-opening knife laws vary by state, city, and municipality. Knifeworks cannot provide legal advice. Check your local laws at akti.org (American Knife and Tool Institute) before carrying, or call us at 888-225-9775 and we will point you in the right direction.

Kershaw offers a lifetime warranty against defects in materials and workmanship. If the knife fails due to a manufacturing defect, Kershaw will repair or replace it at no charge. Warranty service is handled directly by Kershaw — not Knifeworks. Submit a claim through Kershaw's website at kershawknives.com with a description of the issue and proof of purchase. Normal wear, cosmetic finish wear, sharpening, and damage from misuse are not covered.

Marbled carbon fiber requires minimal maintenance compared to natural handle materials. The surface does not absorb moisture, oils, or solvents the way wood or Micarta does. Wipe the handle down with a dry or lightly damp cloth to remove dirt and pocket lint. Avoid prolonged exposure to strong solvents or acidic cleaners, which can degrade the epoxy resin matrix in the carbon fiber layup over time. The handle will not warp, swell, or change dimensionally with temperature or humidity changes, making it an extremely stable carry material year-round.

Yes. The Bel Air 6105CF is manufactured at Kershaw's production facility in Tualatin, Oregon. USA-made Kershaw knives go through domestic quality control and are held to tighter fit-and-finish standards than Kershaw's offshore production line. The 6105CF is part of the Bel Air platform series — all variants in the 6105 series are USA production pieces.
